  "context": "On the evening of Wednesday, January 10, 2018, around 6 PM PST, a [single bullet struck the Visual Arts Building](https://www.cbsnews.com/news/cal-state-san-bernardino-reports-shots-fired/) on the west side of the CSUSB campus, near Parking Structure West. The university immediately issued a shelter-in-place order via its emergency alert system. The lockdown stretched [more than five hours](https://www.nbclosangeles.com/news/local/Cal-State-San-Bernardino-on-Lockdown-Following-Non-Injury-Shooting-468705623.html) as police methodically cleared every campus building, with some students still confined as late as 10:30 PM PST. Investigators eventually concluded that [the bullet had most likely been fired from off campus](https://patch.com/california/redlands/report-shots-fired-cal-state-san-bernardino-investigated) and struck the building incidentally. No suspect was ever apprehended. The incident occurred barely two years after the [December 2015 San Bernardino terrorist attack](https://en.wikipedia.org/wiki/2015_San_Bernardino_attack) just miles away, contributing to the heightened community anxiety during the lockdown.",
  "keyFindings": [
    "The five-plus-hour lockdown for a single off-campus stray bullet illustrates the time required to clear a 430-acre campus once a shooter is suspected",
    "The incident occurred near the second anniversary of the 2015 San Bernardino terrorist attack, sharpening community fear",
    "No suspect was ever found, leaving the case unresolved despite a major multi-agency response"
